The person you mentioned may be me. I’m 75. My urologist is Dr. Kwon of Mayo who referred me to Dr. Hujec for chemo. I was diagnosed Stage 4b metastatic Gleason 9 about 30 months ago. Started Lupron soon thereafter and added darolutamide with chemo. Subsequently did SBRT. Stopped Lupron after 13 months and am still on darolutamide mono therapy. Do PET scans every three months. My PSA is negligible. Dealing with fatigue issues. Physical therapy has helped.
